Boreas – Activated Carbon

Looking for an alternative to Nevermore Carbon? Boreas is Nevermore approved (by the creator of Nevermore Ondsk4) activated carbon for your 3D printer air filtration system.

• Optimal Quantity: Each vacuum-sealed 2.15l (~1kg) bag is enough to completely fill a Nevermore StealthMax
• Customizable Use: Can be mixed 50/50 with Potassium Permanganate (e.g. Nevermore Scorch or Notus) to extend filtration capability.
• Shipped in a resealable vacuum bag to extend shelf life and allow partial use.

Suitable for enclosed 3D printing setups using lower-odour materials such as PLA, PETG and TPU. These materials are not emission-free, but they are generally lower-concern than ABS, ASA and other high-temperature engineering filaments.

Typical properties :

• Moisture (maximum): 2 wt%
• Hardness (minimum): 95 wt%
• Particle Diameter: 3 mm
• Substrate CTC (minimum): 70 wt%
• Substrate Surface Area: 1,250 m²/g
• Ash Content: 12% maximum
• Pressure Drop @ 50 fpm (0.25 m/s): 1.7 in. of water/ft. of bed
